Tqall who'mz't mag/concern;

Be 1t known that I, ANDREW EPPLER, a4

citizen of the United States,` residing at.' Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Thread-Wwf. ing Devices; and I do hereby declare the f ollowing to be afull, clear, and exact descriptionol the invention, such as will'enable the temperature of the wax may be more` others skilled in theart to-which it appertains to make and use` the same. lThis inventionv relates t`0 improvements in thread'waxing devices for sewing machines. The object of the invention 'is tov roduce an improved thread waxing devibeiili which easily and accurately regulated than in the. devices heretofore constructed.

With the above object in View a featureV of the invention contemplates the provision,v

in a `thread waxing device having a steam chamber and a wax pot located adJacent to the steam chamber. of means for permitting a. draft of air to flow between the Wax pot and the steam chamber. preferably has provision for regulating the amount of air Awhich flows between thevst'eam chamber and the wax pot.

In the accompanying drawings illustrat# ing the invention in its preferred form, Fig'- ure 1 is a side elevation partly in section of a thread waxing device and associated parts, and Fig. 2 is a detail sectionalvview of thewax stripper taken on the line 2 2 of Fig. 1. v The present inventionis adivisifn of application Serial No. 275,741, filed August 25. 1905 upon which Patent1\To. 1,030,880 issued July 2, 1912. Inasmuch as the stitch forming mechanism of the machine disclosed in said application forms 'n`0 part of the. present invention, no illustration 0r de-` scrlpticn ofsaid mechanismis 'made in this,

application.

The thread waxingd'evice illustrated in made smaller than the central chamber in the wax pot andl a damper 3 at the bottom 'Y affords means for admitting air" through 1 y holestherein to the .Wax-pot ha m b;e'1".`.jBy-- .openingthe damper moreorle' allarger or" smallr. amount of airlis-j permitted-imp apss; i

The said `means through thelwa'X-pot spac up through the wax pot` chamber and thus the temperature'of the Wax may be very' nicelyl regulated and boiling thereof be 'prevented. The upper end of the wax Apot 2. is provided with-avflange which rests uponthe upper surface of the casing of the steam- 'chamber' 1. To allow for the circulation of the air enteringthrough the amper.3 the upper surface of the casingfof fthe Steam' chamber is .cut away at intervals, as indicated in dotted lines -in Fig. l at 10. The thread passing up fromthe Wax pot .passes through the stripper 4 consisting of a rubber 'gasket and a followerg for compressing the rubber gasket to' cause it tostrip more.v or less Wa'x'from the thread.. The follower 5' is provided with a groove in itsupper .end whichv is adapted to receive the collar ofthe adjusting bolt G. By screwing the adjusting bolt 6 up and down the follower 5 is raised and lowered.` This is regarded as an im prcvement over the use of a screw thread on the follower which has in the past caused considerable trouble by the sticking ofthe.

gasket in the thread. y The thread passes into the wax pot from a suitable source of Sup- Vout of the pot it is guided by the stripper.

From the stripper the threadpasses over the tension wheel 7, a tension spring adapted to be compressed by the hand. wheel 8. is em'- ployed vfor applying resistance to the wheel, and a lever 9 is provided by means of which the tensionn'iay be thrown .011, The thread from the tension wheel'fruns through `the thread tube 10 on its way. to the stitch' forining devices. .i

Having explained the' nature and obiect of the'. 'invention, and having specifically de-A embodiment thereof,-

Ascribed the preferred what is claimed-'is :A "s

' 1. A thread waxing Y device for-wax thread. sewing mach1nes,"hav'1ng, rnfcoibination, an

annular steam. chamber provided with a wax-pot;v space space, threading the thread V-th ;ugh the wax "pot,`a'nd means for permitting a draft fair to flow' A thread' waxing deviY sewing machines, having, in combination, .a steam heatedA chamber, a wax-potk located adjacent to said steam chamber, thread guiding devices for conducting f the thread through the wax pot, and means for permitting a draftl of air to How between the wax-pot and the steam chamber. l Ks 3. A'thread waxing device for Wax thread sewing machines, having, in combination, a 10` steam chamber, a Wax-pot adjacent thereto,

thread guiding devices for conducting the thread through the Wax pot, and means for permitting a draft of air to flow between the steam chamber and the Wax-pot having provision for regulating the amount of such air. 15
